The SiT9002AI differential oscillators for PCIExpress or FB-DIMM applications use built-in spread spectrum technology to reduce electro-magnetic interference (EMI). The differential outputs are configured to comply with the High-Speed Current Steering Logic (HCSL) specification. In addition, 0.5% down-spread spread spectrum technology helps reduce EMI up to 16 dB. Cycle-cycle jitter is 15 ps, enabling designers to use spread spectrum technology without compromising timing margin. The oscillators offer total frequency stability of ±50 PPM over the industrial temperature range (-40°C to +85°C). Configurable features include: power supply voltage: 3.3 V or 2.5 V; package size of 7 x 5 x 0.9 mm or 5 x 3.2 x 0.75 mm; control pin acts as Output Enable (OE) or Spread Disable (SD); and output frequency of 100 MHz or 200 MHz for PCI-Express or FB-DIMM. The SiT9002AI oscillators are currently in volume production. The devices are available in industry-standard footprints. Customized samples are available in 24 hours and production quantities are available in two to three weeks. Pricing for the 100-MHz device in 1000-unit quantities is $7.57.
